The Wyoming State Geological Survey (WSGS) has released a new map showing coalbed natural gas (CBNG) activity in the Atlantic Rim area of south-central Wyoming.

“CBNG activity in the area southwest of Rawlins started in 2000 with a handful of exploratory wells,” said WSGS geologist Scott Quillinan. “As of November, there were 676 wells drilled. Of these, 277 were producing CBNG.”

The Bureau of Land Management (BLM) has approved 2,000 wells for the area – 1,800 for CBNG and 200 for conventional natural gas.

“The map will be useful to the oil and gas industry and the general public. It includes the status and locations of wells, making it very easy to see trends in CBNG activity throughout the area,” Quillinan said.

The map also includes:

BLM leasing units

Associated infrastructure such as compressor stations and pipelines

A side-by-side comparison of a typical lithological log and gamma ray log indicating producing intervals. The lithologic log includes a brief description of the lithology in 50-foot increments.

WSGS Open-File Report 09-7 measures 46 x 39 inches. It is available as a rolled copy for $25 or on CD for $10, plus shipping fees and applicable taxes. The CD includes printable and viewable files along with files that can be loaded into GIS software.
